The seemingly improbable pairing of an aging Shaquille O’Neal and the run-and-gun Phoenix Suns is a “yes” from the Suns away from happening, according to NBA front-office sources.

Sources told ESPN.com on Tuesday night that the Miami Heat are poised to send O’Neal to the Suns in exchange for All-Star forward Shawn Marion and out-of-favor guard Marcus Banks. Miami is just waiting for Phoenix management to either accept or reject what would rank as one of the most unexpected trades in league history.

“It looks like it’s going to happen,” said one source close to the situation. “We should know for sure by tomorrow.”
